Dual OS is what sony do already with the A7ii/rii. Why not if it the hardware is there

Just bought GX7 for good $$$, I am sure the new model will be better but also more expensive.Probably more than
E M5 mkII.

Looks very promising.
I really hope their IBIS implementation will feature similar efficiency to Oly's counterpart.
In terms of shape, I think a rangefinger-style body (i.e. rectangular) makes much more sense than a DSLR-style one. Mostly, because of the pentaprism hump which is totally artificial and a waste of space since there is no mirror!
I'm very curious about the sensor and the AF which seems very sensitive given it's rated at -4EV.

Horizontal crop factor of about 1.36 (using "1.5x crop APS-C" as guide).
20 x 1.36 x 1.36 = 37mp, not 30?
20 x 1.36 x 1.36 = 37mp, not 30?

MFT has a 2x crop factor.
APS-C ~1.5x (or 1.6x for Canon)
Ratio MFT/APS-C is 2/1.5 = 1.3333
Has to be squared for the surface: 1.3333^2 * 20 MP = 35.55 MP APS-C

It would be right if they had the same aspect ratio, but they don't (3:2 vs 4:3). It would be more appropriate to take the diagonal then:
- EM10: sqrt(17.3^2 + 13^2) = approx. 21.64
- D7200: sqrt(23.5^2 + 15.6^2) = approx. 28.21

I agree that one should distract MP's to get a 3 x 2 MP count .
So 37mp would be a 3:4 sensor.
A 3:2 sensor would then be about 33mp.
